Time for our next problem in the POW series! Earlier, Todd and I deliberated for a bit on whether we should pose a “hard” Ramanujan identity (involving an integral and Gamma function) as the next POW, but decided against doing it. Perhaps, we may do so some time in the future.
Okay, the following integral was brought to our attention by Carl Lira, and for the time being I won’t reveal the actual source of the problem.
It is “hard” or “easy” depending on how you look at it!
